QoS Intra Process Communication Issue

edit

Hi everyone, I am working on developing intra process communication using the realsense camera D435i and trying to run this launch file - https://github.com/IntelRealSense/rea... but I am getting this error in the command prompt -

[component_container-1] terminate called after throwing an instance of 'std::invalid_argument'
[component_container-1]   what():  intraprocess communication allowed only with volatile durability

I have all the necessary files in the package. As far as I an understand, it has something to do with the QoS settings but I am not able to figure out how and where exactly should the settings be changed. If anybody has experience of solving this issue, please help me, thank you.
